Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of connecting devices, and in particular to a pin mounting and clamping structure. Background Technology

[0002] In the manufacturing process of connectors, the precise assembly of the ejector pin and the plastic substrate directly determines the product's conductivity and mechanical life. Traditional processes use manual or semi-automatic methods for installation. Operators need to fix the miniature plastic parts on a fixture, then use tweezers to hold the metal ejector pin (PIN pin) and insert it into a solidification hole with a diameter of less than 2mm, and finally use a manual stamping tool to compact it.

[0003] However, the force fluctuation range during manual stamping can reach ±30%. Overpressure will damage the plastic insulation layer, while underpressure will increase the contact impedance of the ejector pins, affecting the stability of high-frequency signals and causing a decrease in the conductivity of the connector. Therefore, it is necessary to improve this. Utility Model Content

[0036] The present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figures 1 to 3 As shown, the present invention provides a pin mounting and clamping structure, which includes a feeding platform 1, a feeding device 2, an insertion device 3, and a clamping device 4.

[0038] The loading platform 1 is equipped with a guide groove 11 for guiding the sliding of plastic parts; the guide groove 11 physically constrains the movement trajectory of the plastic parts, realizing the directional sliding of the plastic parts and avoiding positional deviations caused by manual placement.

[0039] The feeding device 2 is disposed on one side of the guide trough 11 and is used to push the plastic part to slide along the guide trough 11; the feeding device 2 applies a linear driving force to overcome frictional resistance and ensures that the plastic part is continuously conveyed along the set path.

[0040] The insertion device 3 is positioned above the guide groove 11 to convey the ejector pin into the fixing hole of the plastic part; it realizes the vertical alignment of the plastic part hole position to perform the insertion action, and completes the initial positioning and assembly of the ejector pin and the plastic part.

[0041] The clamping device 4 is located on one side of the insertion device 3 and is used to press the ejector pin into the fixing hole of the plastic part. By applying axial pressure to the inserted ejector pin through the clamping device 4, the gap between the ejector pin and the hole wall is eliminated, ensuring the assembly is secure.

[0042] During operation, the plastic part automatically aligns with the sliding trajectory due to the physical constraint of the guide groove 11. The feeding device 2 linearly propels the plastic part unidirectionally along the guide groove 11 to the first processing station. The insertion device 3 vertically inserts the ejector pin into the fixing hole of the plastic part. The feeding device 2 then linearly propels the plastic part unidirectionally along the guide groove 11 to the second processing station. The insertion device 3 applies axial clamping force to the end of the ejector pin to ensure that the ejector pin is assembled to the preset position. This eliminates manual alignment angle deviations and ensures that the interference fit between the ejector pin and the plastic part is consistent, thus guaranteeing the stability of the high-frequency signal.

[0043] This application uses the guide trough 11 to directionally transport plastic parts to the dual workstations, and sequentially completes the vertical insertion and independent clamping of the ejector pins, so as to achieve precise assembly of the ejector pins and plastic parts to ensure the stability of high-frequency signals.

[0044] like Figure 2 As shown, the material conveying device 2 in this embodiment includes a material conveying frame 21, a material conveying slider 22, a material conveying driver 23, and a displacement driver 24.

[0045] The material conveyor 21 is disposed on one side of the material guide trough 11, and the displacement driver 24 drives the material conveyor 21 to move closer to or away from the material guide trough 11;

[0046] The material conveying slider 22 is slidably connected to the material conveying frame 21. The material conveying slider 22 is provided with a plurality of material conveying grooves 221 for limiting the plastic parts. The material conveying driver 23 drives the material conveying slider 22 to reciprocate along the material guide groove 11.

[0047] Specifically, the displacement driver 24 drives the material conveyor 21 to approach the guide groove 11, so that the plastic part is stuck in the material conveyor 221, which makes it easier to push the plastic part; when the displacement driver 24 drives the material conveyor 21 away from the guide groove 11, the material conveyor 221 is separated from the plastic part.

[0048] The material conveyor 21 provides a fixed support base and positions the conveying trajectory reference. It ensures that the movement of the material conveyor slider 22 is parallel to the guide chute 11 to avoid deviation in the thrust direction.

[0049] Multiple independent feed troughs 221 can carry multiple plastic parts at a time. The plastic parts are isolated in time periods to prevent them from colliding or stacking during transport.

[0050] The feed driver 23 linearly drives the slider to reciprocate along the guide chute 11. This actively controls the step-by-step advancement of the plastic part, replacing continuous friction conveying and eliminating the risk of slippage.

[0051] The material conveying driver 23 is a combination of a stepper motor and a ball screw, which enables the material conveying driver 23 to precisely control and drive the material conveying slider 22 to convey a distance along the guide groove 11.

[0052] like Figure 2 As shown, the material feeder 21 in this embodiment is provided with limiting blocks 211 for restricting the sliding range of the material feeder slider 22. Specifically, the limiting blocks 211 are physical blocking structures provided at both ends of the material feeder 21, constraining the movement range of the material feeder slider 22. This precisely controls the reciprocating stroke of the slider, preventing overtravel impacts that could cause displacement of the plastic parts or damage to the equipment.

[0053] like Figure 1 As shown, in this embodiment, a positioning groove 12 is provided on one side of the guide groove 11 for detecting the position of the plastic part in the guide groove 11. By using the positioning groove 12 as a reference for the position of the plastic part in the guide groove 11, the real-time position of the plastic part in the guide groove 11 can be directly sensed.

[0054] like Figure 3 As shown, the insertion device 3 in this embodiment includes a mounting frame 31 and an installation robot 32; the installation robot 32 is disposed on the mounting frame 31, and the mounting frame 31 provides a rigid support structure for the robot's motion reference, isolates external vibration, and ensures positioning accuracy.

[0055] The installation robot 32 includes a longitudinal driver 321, a lifting driver 322, and a gripper 323.

[0056] The longitudinal driver 321 is used to drive the lifting driver 322 to move closer to or further away from the guide groove 11, and to adjust the working distance of the lifting driver 322 and the clamping claw 323 in the horizontal direction to adapt to the material fixing holes of plastic parts of different sizes.

[0057] The lifting driver 322 is used to drive the clamping claw 323 to move closer to or away from the plastic part, and to control the stroke of the clamping claw 323 to clamp the ejector pin into the plastic part in the vertical direction, so as to precisely control the depth of the ejector pin insertion hole.

[0058] The clamping claw 323 is used to clamp or release the ejector pin. By clamping the ejector pin with the clamping claw 323, the radial degree of freedom of the ejector pin is constrained, preventing the micro ejector pin from falling off or deflecting during the transfer process. After the ejector pin has been inserted into the plastic part, the clamping claw 323 releases the ejector pin.

[0059] The lifting driver 322 is a precision cylinder or servo electric cylinder, which drives the gripper 323 to move closer to or away from the plastic part. The gripper 323 is a pneumatic two-finger parallel gripper with an adjustable gripping force of 1-5N, which facilitates the gripping or releasing of the ejector pin.

[0060] like Figure 3 As shown, the insertion device 3 in this embodiment also includes a pin posture adjustment assembly mechanism 5, which adjusts the posture of the pin.

[0061] The ejector pin posture adjustment assembly mechanism 5 includes an adjustment platform 51, an adjustment fixing block 52, an adjustment driver 53, and a detector 54.

[0062] The adjustment platform 51 is located on one side of the mounting frame 31. The adjustment platform 51 provides a rigid platform independent of the robot arm, so as to avoid the adjustment action from interfering with the operation of the installation robot arm 32.

[0063] The adjustment driver 53 is fixed to the adjustment table 51. The adjustment driver 53 drives the adjustment fixing block 52 to rotate. The rotational motion corrects the pin angle deviation, eliminates the pin skew caused by the vibratory feeder, and keeps the pin at a preset angle.

[0064] The detector 54 detects the state of the ejector pin and optically acquires the spatial posture data of the ejector pin to provide real-time feedback for angle adjustment. In conjunction with the adjustment driver 53, it can correct the angle deviation of the ejector pin.

[0065] The adjustment driver 53 is a miniature servo rotary table that drives the adjustment fixing block 52 to rotate. The detector 54 is a combination of a CMOS industrial camera and a coaxial light source, or a laser displacement sensor, to detect the status of the probe.

[0066] like Figure 3 As shown, the adjustment driver 53 in this embodiment is provided with a fixing frame 531, and the adjustment fixing block 52 is disposed on the fixing frame 531. The adjustment fixing block 52 is provided with a fixing hole 521. The fixing frame 531 serves as a rigid support frame that supports the adjustment fixing block 52. The fixing hole 521 mechanically constrains the position of the pin, facilitating the adjustment of the pin.

[0067] like Figure 3 As shown, the clamping device 4 in this embodiment includes a clamping driver 41, a clamping block 42, and a clamping block driver 43.

[0068] The clamping driver 41 is located on one side of the guide groove 11 and drives the pressing block driver 43 to rise and fall; the clamping driver 41 realizes the overall height adjustment of the clamping mechanism, adapts to plastic parts of different thicknesses, and precisely controls the clamping stroke.

[0069] The pressure block driver 43 drives the pressure block 42 to move horizontally closer to or further away from the plastic part. By controlling the precision micro-feed of the pressure block 42 through the pressure block driver 43, the horizontal distance between the pressure block 42 and the ejector pin is precisely controlled, which facilitates the clamping of the ejector pin.

[0070] The clamping actuator 41 is a servo electric cylinder or a pneumatic lifting column, which drives the clamping block actuator 43 to move up and down. The clamping block actuator 43 is a piezoelectric ceramic micro-motion stage or a ball screw module, which drives the clamping block 42 to move horizontally closer to or away from the plastic part.

[0071] like Figure 3 As shown, the pressure block driver 43 in this embodiment is provided with a guide frame 431, and the guide frame 431 is provided with a guide groove 432 that is slidably connected to the pressure block 42. The guide groove 432 constrains the degree of freedom of movement of the pressure block 42, making it easier for the pressure block driver 43 to drive the pressure block 42 to move horizontally closer to or away from the plastic part.

[0072] like Figure 3 As shown, in this embodiment, the pressure block 42 is provided with auxiliary guide strips 421 on both sides. The auxiliary guide strips 421 are slidably connected to the guide groove 432, so that the pressure block 42 moves more smoothly when it approaches or moves away from the plastic part.

[0073] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
